I re-synced on current first thing this morning which is basically midnight
GMT, give or take 1 hr.

I did a complete rebuild via build.sh -u -x -M /usr/obj with clean obj
state.

I installed, and ran etcupdate and confirmed changes to the pam.d/xserver
to put in the current value.

And bing! X stops working via startx and other scripted startups, unless I
put 

	auth	sufficient	pam_self.so

back into pam.d/xserver.

I think this is a regression. I do not think the adoption of PAM should
have changed the ability to run X from a logged in state. 

Please can xserver be updated in current to have this line?
